Things to Keep Your Brain Sharp and Healthy Later in Life
These behaviors and activities are proven to help keep your brain young.
Keep learning new things.
Learning new information and skills throughout your entire life helps to keep your brain strong even in the later years of life. Activities that have the highest value for brain health are novel and complex to each particular person. What is easy for one person may be challenging for another. 1.
Exercise regularly.
Exercise can improve our energy levels, sense of well-being, sleep, and brain health. 2.Identifying why we do not exercise permits us to systematically break down our barriers, and to slowly change our behaviors towards a healthy lifestyle.
Socialize and have fun!
Friends provide opportunities to enable the sharing of experiences, new learning, challenge, emotions, trust, and understanding. Friendship also provides the necessary motivation towards activity and involvement. Engaging in new pursuits with friends often helps develop new life roles, which provide us with an opportunity to feel appreciated, enjoy life, laugh, and have fun. 3.
Be health conscious.
It is important for us to take control of our health and understand that we are in charge of managing of our bodies. 4. Once we establish our own role in the management of our health, the importance of a close and trusting relationship with our physician becomes apparent.
Slow down and appreciate the silence.
5.Our brains require time to process information more deeply, in order to gain more benefit from our daily experiences. A fast-paced lifestyle can cause chronic stress and have other negative effects on our health and well-being. Reducing demands we place on ourselves is an important step towards stress reduction, and a more fulfilling life.
Studies have shown a relationship between spirituality and the immune system. As we continually learn more about the potential of positive thoughts to influence health, people are beginning to integrate these practices more frequently into their daily lives, and experiencing life-changing results.
A. Engaging in it regularly also reduces the risk of depression and anxiety.
B. Reading gives you a unique pause button for comprehension and insight.
C. The things that challenge you the most have the most value for your brain.
D. Physicians work for us, and when it comes to our bodies, we are the boss.
E. Parent-teacher organizations are great places to develop relationships with other people.
F. Open communication can help the physician make sound decisions regarding our health.
G. Our society is developing quickly, leaving us with little time to relax and process our environment.
The argument that human-caused carbon emissions(排放) are merely a drop in the bucket compared to greenhouse gases generated by volcanoes has been making its way around the rumor mill for years. And while it seems to be reasonable, the science just doesn't back it up.
According to the US Geological Survey (USGS), the world's volcanoes, both on land and undersea, generate about 200 million tons of carbon dioxide (CO2) annually, while our automotive and industrial activities cause some 24 billion tons of CO2 emissions every year worldwide. Despite the arguments to the contrary, the facts speak for themselves: Greenhouse gas emissions from volcanoes compose less than one percent of those generated by today's human activities.
Another indication that human emissions surpass those of volcanoes is the fact that atmospheric CO2 levels, as measured by sampling stations around the world, have gone up consistently year after year regardless of whether or not there have been major volcanic eruptions in specific years. “If it were true that individual volcanic eruptions dominated human emissions and were causing the rise in carbon dioxide concentrations, then these carbon dioxide records would be full of spikes —one for each eruption,” says Coby Beck, a journalist writing for online environmental news. “Instead, such records show a smooth and regular trend.”
Furthermore, some scientists believe that volcanic eruptions, like that of Mt.St. Helens in 1980 and Mt. Pinatubo in 1991, actually lead to short-term global cooling, not warming, as sulfur dioxide (SO2), ash and other particles in the air and stratosphere(平流层) reflect some solar energy instead of letting it into Earth's atmosphere. SO2, which converts to sulfuric acid aerosol, when it hits the stratosphere, can linger there for as long as seven years and can exercise a cooling effect long after a volcanic eruption has taken place.
Scientists tracking the effects of the major 1991 eruption of the Philippines’ Mt. Pinatubo found that the overall effect of the blast was to cool the surface of the Earth globally by some 0.5 degrees Celsius a year later, even though rising human greenhouse gas emissions and an El Nino event caused some surface warming during the 1991-1993 study period.
In an interesting twist on the issue, British researchers last year published an article in the peer reviewed scientific journal Nature showing how volcanic activity may be contributing to the melting of ice caps in Antarctica but not because of any emissions, natural or man-made. Instead, scientists Hugh Corr and David Vaughan of the British Antarctic Survey believe that volcanoes underneath Antarctica may be melting the continents ice sheets from below, just as warming air temperatures from human-induced emissions erode them from above.

B.contradict a view held by some people.
C.present new findings for greenhouse phenomenon.
D.report the effects of CO2, in greenhouse phenomenon.
It may seem as if Mother's Day was invented by a company named Hallmark, but people have been taking time on the calendar to give a shout-out to Mom for a long time. The Greeks and Romans had mother goddess festivals — although their celebrations didn't involve the menfolk taking their underappreciated mothers out to dinner. A more recent tradition wasMothering Sunday, which developed in the British Isles during the 16th century. On the fourth Sunday in April, young men and women who were living and working apart from their families were advised to return to their mothers’ houses.
Mother's Day as it is observed in the United States started in the 1850s with Ann Jarvis, a West Virginia woman who held “Mothers' Work Days” to promote health and hygiene(卫生) at home and in the workplace. During the Civil War, Jarvis organized women to improve sanitary conditions for soldiers on both sides, and after the war she became a peacemaker, furthering the cause by bringing together mothers of Union and Confederate soldiers and promoting a Mother's Day holiday.
Jarvis's work inspired another 19th-century woman, Julia Ward Howe. In 1870 Howe published her “Mother's Day Proclamation”, which envisioned the day not as appreciation of mothers by their children but as an opportunity for women to exercise their collective power for peace. Howe started holding annual Mother's Day celebrations in Boston, her hometown, but after about a decade she stopped footing the bill and the tradition faded away.
It was Jarvis's daughter Anna who succeeded in getting Mother’s Day recognized as a national holiday. After her mother died, in May 1905, Anna started holding yearly ceremony on the anniversary and conducting a tireless PR campaign to have the day made a holiday. In 1908 she succeeded in enlisting the support of John W anamaker, the Philadelphia department store magnate and advertising pioneer, and by 1912 West Virginia and a few other states had adopted Mother's Day. Two years later, President Woodrow Wilson signed a resolution declaring the second Sunday in May a national holiday.
It wasn't long, though, before whatever ideals the day was supposed to celebrate were buried under an amount of greeting cards and candy. By the 1920s Anna Jarvis was campaigning against the holiday she had been instrumental in creating. “I wanted it to be a day of emotionalism, not profit,” she said.

“Whatever normal meant”
A pioneering dance group is proving that you can chase your dreams—even in a wheelchair.
Since the age of three, Chelsie Hill had dreamed of becoming a dancer. “The only thing that I loved was dance," she told CBS News. That ambition nearly ended one night in 2010. Hill, then a 17-year-old high school senior in Pacific Grove, California, was in a car accident that put her in the hospital for 51 days and left her paralyzed(瘫痪的) from the waist down. For most people, that would have ruined all the hope of dancing career. For Hill, it was the beginning. “I wanted to prove to my community—and to myself—that I was still ‘normal’,” she told Teen Vogue. “Whatever normal meant, it definitely took a lot of learning and patience.”
After graduation, Hill wanted to expand her dance network to include women like her. She met people online who had suffered various spinal cord injuries but shared her determination, and she invited them to dance with her. Hoping to reach more people in a larger city, Hill moved to Los Angeles in 2014 and formed a team of dancers with disabilities she calls the “Rollettes”. “I want to break down the stereotype of wheelchair users and show that dance is dance, whether you're walking or you're rolling,” she told CBS News. So far, Hill has achieved her childhood dream. But the Rollettes have helped her find more. Every year she holds a dance camp for wheelchair users. She calls it the Rollettes Experience, and in 2019,173 participants from ten countries attended.
For many, it was the first time they'd felt they belonged. Edna Serrano, a member of the Rollettes, says “being part of the Rollettes team has given me the courage and confidence. It's so powerful to have my teammates in my life, because they're my teachers.” The dancers aren't the only ones who feel inspired. One woman saw a YouTube video of the team competing and commented, “You guys are so awesome! I'm in tears because you rock! To be in a wheelchair and still be so beautiful makes me know I can be beautiful too! Thank you! Feel free to find me.”
1.What happened to Hill when she was 17 years old?
A.She got injured while dancing.
B.She just graduated from college.
C.She survived in a traffic accident.
D.She received treatment for a month.
2.What can we know from the passage?
A.Rollettes invite some teachers to train the members.
B.Rollettes aim to help the competitors all over the world.
C.Hill finally realized her childhood dream as a dance teacher.
D.More people become inspired by Rollettes’ performance online.
3.Which of the following words can best describe Hill?
A.Talented and humorous. B.Honest and ambitious.
C.Considerate and generous. D.Optimistic and determined.
